First Tellurium’s PyroDelta thermoelectric generator has demonstrated remarkable durability, operating successfully under extreme temperature conditions far exceeding the capabilities of existing thermoelectric devices. The generator, developed by the company’s majority-owned subsidiary PyroDelta Energy, continues to function at temperatures up to 900°C (1650°F), a significant advancement in the field of thermoelectrics.
PyroDelta’s head engineer, Michael Abdelmaseh, emphasized the significance of the technology, stating, “Operating at 900°C enables the generator to be used in virtually any industrial or technological application.” He explained that even at 600°C, the device would be suitable for the most extreme industrial uses. In contrast, existing thermoelectric devices typically fail or even melt at temperatures around 150°C.
Recent tests have shown the PyroDelta generator’s ability to withstand direct heat from a propane torch, while a standard thermoelectric module deteriorates rapidly under much lower temperatures from a hot air soldering gun. Abdelmaseh noted that this durability opens the door to a range of potential applications, especially in industries that produce high levels of waste heat, such as industrial furnaces and kilns.
Exploring Waste Heat Recovery in Data Centers
The development of the PyroDelta generator has sparked interest from a variety of energy-intensive industries, particularly in the AI and cryptocurrency sectors. These industries generate vast amounts of waste heat, presenting an opportunity for the PyroDelta technology to harness this heat and convert it into renewable power. According to First Tellurium President and CEO, Tyrone Docherty, the company has received numerous inquiries since an article featuring PyroDelta was published in USA Today in December. He highlighted the potential benefits for data centers, where the generators could reduce energy costs and ease the strain on energy grids by capturing excess heat and generating supplemental power.
Focus on AI and Automotive Applications
Docherty added that while the company is exploring several market opportunities, the primary focus remains on developing working prototypes for AI data centers and a thermoelectric radiator/generator designed to replace automobile alternators. The radiator/generator works by generating electricity from the temperature difference between hot liquid flowing through a thermoelectric pipe and air cooling it from the outside.
First Tellurium aims to install a working prototype of the automobile generator by April 2025. “Given the challenges the electric vehicle (EV) industry is facing, even small savings in energy consumption could be crucial for automakers in the years ahead,” said Docherty.
Government Support for AI Data Centers
The potential for utilizing waste heat from AI data centers has gained further momentum with U.S. President Joe Biden’s recent executive order, signed on January 14, which provides federal support for AI data centers’ growing energy needs. Biden noted the increasing demand for computing power and electricity, particularly for training advanced AI models, and predicted a surge in these needs in the coming years.
Docherty highlighted the advantages of colder climates, noting that regions like northern U.S. and Canada, with their lower temperatures, are becoming ideal locations for data centers. These environments enhance the effectiveness of PyroDelta’s technology, making it a strong candidate for addressing the energy challenges in the sector.
Stock Option Grant
In a related development, First Tellurium announced the granting of 1.7 million incentive stock options to directors and consultants. These options, exercisable at $0.15 per share, are valid for a period of 10 years.
As PyroDelta’s technology continues to show promise in addressing high-temperature challenges, the company is positioning itself as a leader in thermoelectric innovation with applications that span various industries.
